Application led September 22, 1917. Serial No. 192,733.l

To all whom t may concern Be it known that I, JOHN B. LooKiiR, a citizen of the United States, residing at St. Louis, in the county of Saint Louis City and State of Missouri, have invented new and useful Improvements in Submarine Boats, of which they following is a specification.

This invention relates tol submarine boats,

and one of `the objects is to provide a certain novel arrangement of-air tanks, with` means for protecting the'v latter, and means for supplying'air to the tanks and the intethe central portion being provided withV av chamber or series of chambers forsuch use as'may be desired, the upper centra-l portion being provided with air chambers and additional air chambers being provided on thek outer sides and extending longitudinally of the vessel, the chambers last mentioned being` protected from injury by certain novel structure described below.

The sides of the vessel carry ar plurality` of air tanks extending longitudinally along the main axis of the hull, the tanks being designated 50 and preferably formed in the manner shown although any suitable con` struction may be employed. These air tanks are protected by guard members 51V extending longitudinally with reference to tank 50 and providing an open chamber 52 between the guard or shield and the tank 50. Valves 54 admit'air from the tank to the interiorof the vessel. The tanks are of course supplied when the vessel is at'the surface. Valves 55 are located as shown and perinitthe entrance of air when said valves, arev open for the purpose of supplying air to the tanks menytioned. The guard members 5l include upper and lower lplane surfaces converging'as shown and adding to the stability of the vessel.V They are well adapted to resist lat-v eral'strain, and effectivelyv protect the air tanks.

What is claimed is :y

In a device of the'class described, a hull including a plurality of compartments and air chambers, an additional air chamberlocated on each side of the hull and projecting laterally therefrom, the upper and lower walls of the additional chambers converging at their outer portions, means for admitting air to the chambers last named, rand means for protecting each of the chambers last named, comprising a guard member extending longitudinally thereof, providing converging supporting surfaces.

In testimony whereof-I afliX my signature.

JOI-IN Bg., LOCKER.
